Running a Gigabyte U4UD, been having battery problems for months now, and the battery health only reports 50% capacity. Started playing Battlefront and got distracted and saw my battery looks like this now. Been doing this for 15 min, so either my battery is magical… or the Clevo design is flawed. Seeing how long she goes for on battery before it just dies.
I am not looking for tech support, just thought this would be funny.
Turn it back on, and go into the BIOS and leave it on, unplugged. This will prevent the OS from turning the machine off so the battery can completely discharge.
Let the battery completely drain until the machine shuts off and won’t turn on again. If this step lasts several hours (like 3 or more hours), it’s likely this procedure will work. The longer it takes, the better the result will be. If it lasts less than 1 hour, this procedure won’t work.
Plug it in and leave it off.
Leave it plugged in until it completely charges. Probably around 8 hours to be safe.
After that, turn it on and check your battery health.
It should now work again if the battery itself isn’t bad.
Note: this procedure permanently reduces the capacity of the battery, so it should only be done as a last resort before just replacing the battery.
Sometimes it is enough to just drain the battery until OS shuts you down and after that let it charge to 100% with no interruptions (best not using the device at that time)
It may need multiple cycles
doing this about once a month should keep the "OS“ of the device (every device with a rechargeable lithium battery (phones, drills, cars, etc.)) calibrated with the actual SoC (state of charge) of the battery.
Either Linux has no idea what your battery is telling it; or your battery is just…toast.
Let’s just hope for your sake it’s just a funny linux bug. Replacing specific laptop batteries can be a tremendous pain if you can’t find a specific cell that works for your device.
Nah, she’s toast. Ran multiple distros, and the same problem persisted across Fedora, Arch, and Ubuntu. It’s also an Intel machine, and I’ve been eyeing a Framework with AMD. Which is why I’ve stated I am not looking for tech support.
How is it that one cannot purchase a bunch of flat rectangular batteries and just put them inside the laptop (wherever they fit) and connect them manually to some custom charge controller? We do it all the time on other devices like drones and shit. We have generic round cylindrical batteries, why isn’t there flat generic Li batteries?
I fear you‘d had to reverse engineer some proprietary nonsense that some companies put in their battery in order to prevent free repai… rhmm, security of course, security…
I’ve not worked with batteries but I would assume there are two pins for voltage and ground, one temperature probe pin and or two pins for serial communication (probably I²C). If batteries would have had some sort complex handshake then it would have needed a corresponding UEFI patch so that system is able to refuse booting if the power level is too low. That’s why I assume there would be no handshake (unless it’s apple ofc).
I’d say the motherboard firmware checks if the battery through those two extra pins you correctly assume to have (there are generally 5 pins). And if the battery is not original it refuses to charge the battery.
You can always boot using power adaptor even without batteries and even on apple laptops 😇
You would be surprised how hard it can be sometimes to source batteries due to shipping rules and regulations; as well as the general difficulty surrounding just building your own battery pack…which can end badly if you aren’t an electronic engineer or similar professional who knows exactly what they are doing.
